Which of the following is a cause of hirsutism?

1. Genetic disposition

2. Excessive sun exposure

3. Pituitary hypersecretion, adrenal tumors, ovarian tumors

4. Insufficient exercise

The correct answer is: Pituitary hypersecretion, adrenal tumors, ovarian tumors

Hirsutism is characterized by excessive hair growth in areas typically associated with male-pattern hair distribution, and its causes can be multifaceted. One significant group of causes includes hormonal imbalances and various medical conditions that affect hormone production. The mention of pituitary hypersecretion, adrenal tumors, and ovarian tumors relates directly to conditions that disrupt normal hormone balance. These factors can lead to increased androgen levels, which contribute to hirsutism. For instance, adrenal tumors may produce excess androgens, while ovarian tumors may increase the levels of hormones that lead to hirsutism. Pituitary hypersecretion can also affect hormone interactions, ultimately leading to elevated androgen production. Therefore, this answer provides a precise connection between hormonal issues and the manifestation of hirsutism, highlighting the role of underlying medical conditions in its development. In contrast, genetic disposition offers a potential risk factor rather than a direct cause. Although genetics can influence hair growth patterns, it does not trigger the conditions like those caused by adrenal or ovarian tumors. Excessive sun exposure might affect skin characteristics but does not correlate with hirsutism, as it does not influence hair follicle activity related to androgen levels. Insufficient exercise might impact overall health and hormone regulation indirectly,
